The "battery issue" is only such for nay-saying armchair experts, but is certainly not an important factor for choosing a body in real life.
Except that it can, and often does, compromise the usefulness and function of an old camera whose metering accuracy can be iffy, at best. The workarounds involve a degree of wishful thinking and inconvenience that really defeats their purpose. If you want to shoot a relic and to skip futzing around the Wein cells, hearing aid batteries and converters that don't always fit, just get a handheld meter. That's the best "real life" suggestion--unless, of course, sitting in your armchair watching a meter needle twitch, matters more.
There are good and bad solutions for the battery issue. If you use a proper adapter or get the lightmeter adapted to a different voltage there is no battery issue any more. Wein cells and hearing aid batteries are only the second best choice IMHO.
The future belongs to the few of us still willing to get our hands smell like fixing bath.
